Have three 9300T machines in use. 1. Has recorded 174 progs and still ok for space. 2. Has recorded about 26 progs and now has problems. - no space left. 3. Is basically a spare backup with a few progs on so do not know it's potential yet. All up to date with recent updates. Machine 2 decided the disc was full at about 26 and refused to record any more progs until a prog was deleted to make room. The progs are mainly 1/2 to 1 hour docs. This situation cannot be right. Have I a major problem here with a duff HD? I have a mind to try to resolve this by formatting the drive but do not know how.(I'm ok formatting PC drives but PVR's are a mystery). Any help with formatting and/ or any other advice appreciated to solve this problem. Number 3 machine is no longer the spare and I now have a spare backup capable of a paltry 26hrs of viewing Cheers.
